This patch implements the following gettext features, as 
discussed recently in python-dev: 
 
In _locale module: 
 
- bind_textdomain_codeset() binding 
 
In gettext module: 
 
- bind_textdomain_codeset() function 
- lgettext(), lngettext(), ldgettext(), ldngettext(), 
  which return translated strings encoded in 
  preferred system encoding, if 
  bind_textdomain_codeset() was not used. 
- Added equivalent functionality in install() and 
  translate() functions and catalog classes. 
- Documentated every change.
